/react-native-ndk-benchmark

Primary LanguageC++

This project is a React Native app that performs benchmarks oriented at different JSI-related tasks.

Currently it only supports Android and uses google benchmark library to run a series of tests written here.

In order to run benchmarks on your own you need to build and install the app. Preferably run benchmarks on a real device and not emulator to get a better sense of the real-life values of the things under test.

Step 1: Install project dependencies

yarn start

Step 2: Build Android's app for release

cd android && ./gradlew assembleRelease

Step 3: Install on Android device

Connect your android phone, and install using ADB:

adb install ./app/build/outputs/apk/release/app-release.apk

Step 4: Launch the app and see results

Launch AndroidBenchmark app installed in the previous step on your phone. Once the app opens, the benchmark results will be writted to ADB logcat. Use the following command to filter the results:

adb logcat | grep BENCHMARK

The output will looks something like that (the below results are from Samsung Galaxy J3 device):
